Abstract: RATE CONTROLLED DIRECTIONAL SOLIDIFICATION METHOD AND APPARATUS                   ABSTRACT OF THE DISCLOSURE     An improved method of directional solidification is provided by varying the rate of withdrawal of a casting from the hot zone of a solidification furnace according to the sense of change of the perimeter to area ratio of the casting.  The rates are varied to achieve desired microstructure and resultant properties in the casting.    Also, the rate of withdrawal is varied according to controlled and predetermined relationships to cause the solidification interface to move through a transition section connecting sections of differing perimeter to area ratios in a manner which produces a desired micro-structure in a first, transition, and second sections.

Abstract: KNIFE WITH BLADE LOCKING MECHANISM                 (Abstract of the Disclosure) A knife of the type having a blade which is selectively pivotally movable between extended and retracted positions relative to a handle.  A rocker arm received between a pair of handle side portions is pivotally affixed thereto at the handle forward end and includes a locking member depending therefrom which is lockingly received in a knife blade locking notch when the blade is in the extended position.  A leaf spring also disposed between the handle side portions acts against the rocker arm to continuously pivotally urge the locking member into engagement with the knife blade locking notch.  The rocker arm extends axially outward from the rear of the handle side portions and has a pair of rear bolster members affixed thereto.  These rear bolsters are selectively movable relative to the rear end edges of the handle side portions against the force of the leaf spring.  Such movement pivots the rocker arm about its pivot mounting to move the locking member out of the locking notch and allow the knife blade to be moved to the retracted position.  The rear bolsters are dimensioned and configured so that when the blade is in either one of the extended or retracted positions, they appear to be integral with the overall handle construction.

Abstract: ABSTRACT The use of an overhead projector equipped with a roll of transparent writing-film has replaced the blackboard in many school classrooms.  As with blackboards, writing can be erased from a film roll (providing the writing has been done with overhead projector pens that have water-soluble ink), and the roll can he re-used.  Most teachers clean their writing-film rolls by slowly winding the film across the overhead projector, stopping frequently to wipe the writing from the film with water-dampened paper towels.  However, writing-film rolls are over fifteen meters (fifty feet) in length, so wiping a roll by hand tends to be a time consuming and messy job,  Usually fifteen to twenty minutes are required and by the time one is finished, one's hands and shirt cuffs are stained with ink.  A busy teacher is inclined, naturally, to avoid the job and use a brand new roll.  Hence, schools expend around twenty dollars apiece on dozens of new rolls while dozens of inky but otherwise usable rolls are being stacked away on shelves,  My invention is a machine that can wash water-soluble ink off a writing-film roll, and dry the film in much less time and with much less mess than is possible when wiping by hand.  With this machine, a person cranks the film from one spool to another as jets 1.     of water wash the ink off the film, and rubber blades wipe the film dry.  The machine can transform an inky roll into a dry, clean roll in under three minutes, without getting ink on one's hands or clothes.   2.

Abstract: D22,469 CURRENT SENSING CIRCUIT FOR POWER SUPPLY     WITH SERIES CONTROL TRANSISTOR              by Robert G. Rogers ABSTRACT OF DISCLOSURE A -DC to +DC voltage converter having one input and one output terminal connected to ground and regulator circuitry responsive to a control voltage for regulating the magnitude of output current delivered to a load impedance connected across the output terminals. Apparatus producing the control voltage comprises a passive resistive bridge circuit having one pair of nodes connected between the other input and other output terminals and a current sensing resistor in one arm of the bridge so as to pass load current to the other output terminal, a difference voltage that is the control voltage being developed between the second pair of nodes of the bridge.  In one embodiment, the bridge comprises a potentiometer having a moveable contact connected to the other input terminal, and first and second pairs of series connected resistors connected between opposite sides of the potentiometer and opposite sides of the current sensing resistor.  The potentiometer is adjusted to make the difference voltage between junctions of resistors of the pairs thereof a desired value for a prescribed maximum load current in the current sensing resistor.  In an alternate embodiment that is also responsive to input current, the potentiometer is replaced by a fixed resistor connected to the other input terminal and having opposite sides thereof connected to ends of associated series connected resistors, one of the other resistors being variable for adjusting the bridge.

Abstract: BANKING MACHINE CONTROL          Abstract of the Disclosure The present invention relates to a method and apparatus for controlling the dispensing of bank notes from a banking machine which is responsive to externally generated control signals.  The apparatus is comprised of a transport unit for delivering bank notes from a storage bin along a transport path to an escrow station.  A unit is provided which is responsive to multiple notes entering the transport unit to return all but one note to the storage bin.  A sensor senses the movement of a note along the transport path to generate a note timing and note count signal.  A multiple note detector is located downstream of the sensor along the transport path by a distance less than the length of a bank note and responsive to the note timing signal to sense multiple notes traveling together through the transport unit.  The multiple note detector generates a divert required signal for a multiple note condition.  A transport unit is provided for transporting notes assembled in the escrow station to an exit throat if the multiple note detector does not sense multiple notes traveling together.

Abstract: ABSTRACT OF THE DISCLOSURE;           A process for an efficient production of cheese or cheese base containing substantially all the casein and whey proteins which were originally present in the milk comprising four phases: (1) selective concentration of milk to form a concentrate; (2) increasing the ionic strength of the concentrate so as to maintain it in the liquid phase during fermenting; (3) fermenting the concentrate; and (4) removing water from the fermented concentrate to produce cheese or cheese base containing substantially all the casein and whey proteins originally present in the milk.   The concentrates and fermented concentrates are unique intermediate products in that they do not coagulate during processing even at low pH's.            The process permits an efficient evaporation of water from the fermented concentrate that is maintained in the liquid state. The process also avoids the possibility of losing whey proteins by totally eliminating syneresis.
